Is positioning the cursor and pushing the "N" key too much for you ? I suppose if clicking on 'Help' , or looking at the manual is too much, then maybe it is ....
'N' will pop in a new track number. 'Shift/N' will put in an Index marker if you prefer that approach.
Thanks, I guess. I have been searching in the help file, but didn't realize that I needed to search for Track unstead of Chapter. Sorry for being stupid.
